Description
Technical field
The present invention relates to a kind of stage sound gathering device.
Background technology
Large-scale arenas, when performance concert, often, because of its huge stage space, spreads and has absorbed most of music energy, when especially playing, singing without the primary sound of public address, and micro-its emblem of happy power of former times that auditorium is received, music effect is had a greatly reduced quality.For making auditorium reach desirable Qu Yinxiao and acoustic pressure. just need to seal before the lights and build anti-acoustic shell, the increase reverberation time beautifies tone color and recalls by force playing effect, and increase early reflection, make sound reflex to forward auditorium, rather than disappear to top, rear and the both sides of offstage, make audience in large arenas, enjoy beautiful tone color as close at hand in player in concert hall.
Anti-acoustic shell is mainly divided into two zhang of excrement: ground running formula and overhead suspension are hanging.Aerial underslung anti-acoustic shell is suspended on stage top.In only having the arenas of music items on the program, how anti-acoustic shell fixedly hangs on above match platform, and what have only installs top plate, and top and back panel are installed when also having.In multi-functional large-scale arenas, adopt multi-disc portable plate to form anti-acoustic shell, by upper plate, rear plate, left reflection pull, right panel four major parts form; While not using, being suspended on respectively collection position separately, stage top, is the suspension rod vacating spaces such as the light above stage, setting; When performance needs, make it to fall, and arrive and use position through certain running orbit, be built into the anti-acoustic shell of ridiculing mouth-shaped, opening is towards spectators. and make reflect sound point to auditorium.
The anti-acoustic shell of suspension type is performed the impact of setting in order to reduce plate shared space and reduction when collecting to other, in the mutual transfer process of building and collecting at lattice, plate will a series of horizontal and vertical overturn through ground, and the complicated running orbit of displacement etc. just can complete.After general, plate is fairly simple, only needs vertical lift can form the back reflection wall of anti-acoustic shell.Upper plate is horizontal tilt state while using, and hangs on the ceiling that anti-acoustic shell is formed on top, rotates it for plumbness during collection, then rises to collection position.
More complicated in the anti-acoustic shell of suspension type is left, and the composition of right biside plate and motion mode, mainly contain two kinds of modes.The first is that the side plate of anti-acoustic shell is comprised of two of left and right, vertical with scape bar during collection, hangs on the space of top, stage both sides; During performance, through vertical, decline. to the traction of stage entablature, be shifted and horizontally rotate certain angle. red one-tenth Eight characters opening shape, finally and top board and rear plate be jointly built into anti-acoustic shell.The second is that left side plate is comprised of several piece longitudinal type platelet respectively, during collection and the top of scape bar parallel suspend in the middle of stage; When performance is used, decline and discharge the traction that makes each side plate deflection stage middle upper part, when making it to decline, to two side shiftings, when arriving use location pair, again by operating personnel by special nearly 90 degree of each little side plate rotation, then each platelet assembling link of smoothing out with the fingers both sides becomes two large side plates, with top board and after pull common mushroom and build up anti-acoustic shell.
Above two kinds of modes solve building and collecting of anti-acoustic shell preferably, but also come with some shortcomings.As the second way, side plate need take multiple tracks suspension rod position, taken more the anxiety of stage middle upper part empty with, can make the utilization of setting and light in performance from now on of this stage be restricted, the performing effect of the Long-term Effect arenas, and installing and collection needs plate splicing in a plurality of minutes in to journey, running orbit is complicated, it is cumbersome to operate, and must many people coordinate to install to assemble, consuming time taking a lot of work, in erection schedule, be easy to bump against with other facilities and setting, have certain danger, safety is poor.Although first kind of way is installed and collection is relatively simple, does not take nervous stage superjacent air space, stop go out to drill ashamed person's sight line of 2 layers of bridge, and have with the second way equally that running orbit is complicated, there is the common issue with such as potential safety hazard in installation and collection.
Summary of the invention
The present invention aims to provide a kind of saving collection space, the anti-acoustic shell of quick and easy for installation and safe stage.
The anti-acoustic shell of stage of the present invention, comprise rear plate, rear plate is left and right, top is respectively provided with left and right side plate and top board, afterwards, left side, right side form together with top board one hood-shaped, and left and right side plate bottom is equipped with a field door, also comprise a lifting truss parallel with stage scape bar, left and right side plate is suspended on truss and with truss and is rotatedly connected.
Preferably, described left and right side plate is suspended on truss by walking dolly.
Or preferably, truss also with top board, rear plate is parallel.
The anti-acoustic shell of stage of the present invention has the following advantages:
(1) overall structure is simple, 4 musical panels, consists of;
(2) two side plate unifications are installed under a truss, have simplified widely two side plate movement locus and control mode;
(3) occupy little space, 4 plates are parallel consistent with the installation direction of the equipment such as lamp stand scape bar of stage top, remove top and pull outside the space that must take with rear plate, and side plate only takies suspension rod space, l road, has saved to greatest extent space.
